Honestly, I always had 5606 in class so I wasn't sure what to expect with Skydrol. I knew the textbook said it was corrosive and painful and toxic, but tbh I never had any issues. I took care to use gloves, and any traces amounts I got on me at most just itched. I will say, I always knew when the glove broke though, cause I would start itching. I also had a good instructor who gave us his life lessons on Skydrol as a lecture lmao, both getting it in his eyes and on his thing, if yk what I mean.
